Question of Red Space Glow Solved

While I wish that this article was a lot longer, it does get across the pertinent point. Apparently galaxies glow red and no one has been able to explain why, until now. Scientists now think that the coloring is due to molecular forces on a very, very small scale. The glow comes from carbon-rich molecules called polycyclic aromatic hydrocarbons, which have been bombarded by UV radiation to make them red. Normally such molecules would disintegrate under such conditions, but the scientists pulled out some complicated math to determine that there should be a way for this to actually occur. So, one more mystery of the universe (even though I never knew about it before now) probably solved.
